Follow These Steps
Cut the top, then slice in half
Using a sharp chef’s knife, slice about a half an inch off the top of the onion and discard. Turn the onion to rest on this flat end and slice in half vertically.
Tip: If you’re only using half of the onion, leave the skin on and wrap what you’re not using in plastic wrap.
Peel off the papery layers
Remove and discard the skin.
Take one onion half and lay it flat on your cutting board. Holding the root end, carefully cut vertically, making sure not to slice all the way through.
Tip: Leave the root side intact to make chopping easier.
Rotate the onion and slice vertically down through the onion, still leaving the root end intact. Discard the root end and repeat with the remaining half of the onion.
Tip: The closer together the initial horizontal and vertical cuts are, the smaller the dice.
